Back on page 4 I posted a WD pulley speed Question and Joe M from Georgia posted a nice picture of the pulley assembly. Mine appears to be a little different than the one posted. The seal on the end of the shaft on my assembly has a bushing pressed into the housing, then the seal in pressed into that bushing. In the assembly that is pictured the outside diameter of the seal is the same diameter as the housing. Has my assembly been reworked or is there two different assemblys. Would anybody have a seal number for the smaller outside diameter seal? The seal I have has metal on both sides and the seal itself is made of leather or something similar. There are no numbers on my seal. Any suggestions? Thanks
